Neonatal jaundice is one of the common symptoms during the neonatal period. It can be a normal physiological phenomenon or a manifestation of certain diseases. Jaundice is generally divided into physiological jaundice and pathological jaundice. Physiological jaundice does not appear very early, progresses slowly, lasts a short time, and is not very severe. Generally, for jaundice monitoring, it is recommended that newborns be closely monitored for changes in jaundice. Jaundice within 24 hours after birth generally does not exceed 6 milligrams per deciliter. From 24 to 48 hours, it generally does not exceed 9, and from 48 to 72 hours it does not exceed 12. After 72 hours, the jaundice level should not exceed 15. If monitoring shows that the jaundice level exceeds the normal range, it is advisable to go to the hospital promptly. The doctor will then determine the specifics of bilirubin levels in the blood. If bilirubin in the blood is indeed elevated, timely intervention and treatment are recommended.
